I-11 signThe first phase of Interstate-11 involves traffic improvements to U.S.93 in the Boulder City, Nevada area. The proposed project limits are between a western boundary at the end of Interstate 515 on U.S. 93/95 in Henderson near the Foothills grade separation approximately one mile north of the Railroad Pass Hotel and Casino and an eastern boundary on U.S. 93, approximately 4.7 miles east of downtown Boulder City. The eastern boundary borders the western end of the U.S. 93 Hoover Dam Bypass project.

U.S. 93 is a major regional commercial corridor for interstate and international commerce. It is the single route through Boulder City and functions as a major urban arterial. It is also a direct north-south link between Phoenix and Las Vegas, which are two of the fastest growing areas in the United States. It averages 32,000 vehicles per day of east-west traffic from Interstate 40 to Las Vegas and Interstate 15. U.S. 93, in combination with I-19 (Nogales to Tucson) and I-10 (Tucson to Phoenix), create a continuous Canada-to-Mexico corridor. In Nevada, U.S. 93/U.S. 95 is a four-lane divided facility from Las Vegas to the west study limits.

Within the study corridor, U.S. 93 varies from a four-lane divided roadway to a two-lane roadway with numerous business driveways and cross streets. The highway project would provide overall transportation improvements by reducing traffic congestion and crashes and enhancing regional mobility, while maintaining or improving local access within Boulder City.

  • Improves operations for trucks from U.S. 95 to U.S. 93
  • Improves operations for peak trips from Boulder City to Las Vegas
  • Improves local circulation
  • Reduces truck traffic through Boulder City
  • Completes initial bypass phase

The project is separated into two phases, shown in the exhibit below.
